2. Noise gate - Wikipedia

   en.wikipedia.org/wiki/Noise_gate

   An Alesis Micro Gate noise gate. A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal.Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold.

3. Dynamic range compression - Wikipedia

   en.wikipedia.org/wiki/Dynamic_range_compression

   Downward expansion makes the quiet sounds below the threshold even quieter. A noise gate can be thought of as an extreme form of downward expansion as the noise gate make the quiet sounds (for instance: noise) quieter or even silent, depending on the floor setting. [2] Upward expansion makes the louder sounds above the threshold even louder.

4. Squelch - Wikipedia

   en.wikipedia.org/wiki/Squelch

   A noise squelch circuit is noise-operated and can be used in AM or FM receivers, and relies on the receiver quieting in the presence of an AM or FM carrier. To minimize the effects of voice audio on squelch operation, the audio from the receiver's detector is passed through a high-pass filter , typically passing 4,000 Hz (4kHz) and above ...

5. Ducking - Wikipedia

   en.wikipedia.org/wiki/Ducking

   Ducking here works through the use of a "side chain" gate. In other words, one track is made quieter (the ducked track) whenever another (the ducking track) gets louder. This may be done with a gate with its ducking function engaged or by a dedicated ducker. A typical application is to achieve an impression similar to the "pumping" effect. The ...

6. Noise-canceling microphone - Wikipedia

   en.wikipedia.org/wiki/Noise-canceling_microphone

   The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .

9. Audio signal processing - Wikipedia

   en.wikipedia.org/wiki/Audio_signal_processing

   Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals.Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions.
